INDICATORS AND CONTROLS ON THE SMART-UPS

The APC Uninterruptible Power Supply (UPS) is designed to prevent blackouts, brownouts, sags and surges from reaching your computer and other valuable electronic equipment. The UPS filters out small utility line fluctuations and isolates your equipment from large disturbances by internally dis- connecting from the utility line. The UPS provides continuous power from its internal batteries until the utility line returns to safe levels.

The Smart-UPS has the power control and operating indicators located on the front panel. The rear panel has the input and output connectors.

SMART-UPS FRONT PANEL

The ON and OFF buttons are used to power the UPS and act as master controls for the connected equipment. (Make sure connected loads are switched to their ON position) The UPS remains on as long as it is attached to utility power.

OPERATION

Power On

Power Off

Load

Press and release the button labeled, TEST, to supply power to the UPS and connected equipment. The equipment is immediately powered and the UPS performs a self-test.

The charger maintains battery charge when the UPS is plugged in and utility voltage is present.

Press and release the button labeled, 0, to turn off power to the UPS and connected equipment.

The five-LED display on the left of the front panel shows the percentage of available power used by the connected equipment (load). For example, if three LEDs are lit, the connected load is drawing between 50% and 67% of the UPS capacity. If all five LEDs are lit, the connected load is drawing between 85% and 100% of capacity. Thoroughly test your entire system to make sure that the UPS will not become overloaded. In the graphic to the left, the load capacity threshold is listed next to the LED (these are not shown on the actual UPS).
